CHAPTER 6: SYSTEM DESIGN AND INTEGRATION TOOLS

This chapter introduces MAPP, Meyer Sound's patented
system design tool, and SIM, a comprehensive system for
measurement and analysis.

MAPP SYSTEM DESIGN TOOL

The MAPP System Design Tool (Figure 45) is a powerful,
cross-platform application for accurately predicting the
coverage pattern, frequency response, phase response,
impulse response, and SPL capability of single or arrayed
Meyer Sound loudspeakers.

Whether planning for fixed installations or for tours with
multiple venues, use MAPP to accurately predict the
appropriate loudspeaker deployment for each job, complete
with coverage data, system delay and equalization settings,
rigging information, and detailed design illustrations. MAPP's
accurate, high-resolution predictions ensure that systems
will perform as expected, thereby eliminating unexpected
coverage problems and minimizing onsite adjustments.
The key to the accuracy of MAPP's predictions is Meyer
Sound's exhaustive database of loudspeaker
measurements. Performance predictions for each
loudspeaker are based on 720 1/48th-octave-band
measurements taken with a SIM audio analyzer in the Meyer
Sound anechoic chamber. The extraordinary consistency
between Meyer Sound loudspeakers guarantees that
predictions from MAPP will closely match their actual
performance.
MAPP client software lets you configure Meyer Sound
loudspeaker systems and define the environment in which
they operate, including air temperature, pressure, humidity,
and even the location and composition of surfaces. You can
also import CAD (.DXF) files containing detailed venue
information to act as a visual aid.
MAPP prediction requests are sent by the client software to
Meyer Sound servers, where complex, high-resolution
(magnitude and phase) polar data is processed with
sophisticated acoustical prediction algorithms. The resulting
predictions are then displayed in the MAPP client software.
TIP: Meyer Sound offers seminars and webinars
on using MAPP. For more information, visit

MAPP Capabilities
With MAPP, you can:
• Simulate different loudspeaker configurations to refine
system designs and determine the best coverage for
intended audience areas
• Model loudspeaker interactions to locate constructive
and destructive interferences so that loudspeakers can
be re-aimed and repositioned as necessary
• Place microphones anywhere in the sound field and
predict loudspeaker frequency response, phase
response, and sound pressure levels at each microphone
position
• Determine delay settings for fill loudspeakers using the
Inverse Fast Fourier Transform feature
• Preview the results of signal processing to determine
optimum settings for the best system response
• Automatically calculate load information for arrays to
determine necessary minimum rigging capacity, front-to-
back weight distribution, and center of gravity location
• Generate and export system images and full-system PDF
reports for client presentations
